A company has two AWS Direct Connect links. One Direct Connect link terminates in the us-east-1 Region, and the other Direct Connect link terminates in the af-south-1 Region. The company is using BGP to exchange routes with AWS. How should a network engineer configure BGP to ensure that af-south-1 is used as a secondary link to AWS?

Chose B1
The local preference value determines the relative importance of routes received from different BGP peers; a higher value indicates a more preferred path. By setting the local preference value to 50 on the Direct Connect peer to us-east-1 and 200 on the Direct Connect peer to af-south-1, the network engineer ensures that the af-south-1 link is preferred over the us-east-1 link unless the primary link fails. If the af-south-1 link goes down, BGP will use the us-east-1 link because it has a lower local preference value (50) than the af-south-1 link (200).
